.SH "DESCRIPTION"
.PP
\fBxsltproc\fR
is a command line tool for applying
XSLT
stylesheets to
XML
documents\&. It is part of
\fBlibxslt\fR(3), the XSLT C library for GNOME\&. While it was developed as part of the GNOME project, it can operate independently of the GNOME desktop\&.
.PP
\fBxsltproc\fR
is invoked from the command line with the name of the stylesheet to be used followed by the name of the file or files to which the stylesheet is to be applied\&. It will use the standard input if a filename provided is
\fB\-\fR
\&.
.PP
If a stylesheet is included in an
XML
document with a Stylesheet Processing Instruction, no stylesheet need to be named at the command line\&.
\fBxsltproc\fR
will automatically detect the included stylesheet and use it\&.
.PP
By default, output is to
stdout\&. You can specify a file for output using the
\fB\-o\fR
or
\fB\-\-output\fR
option\&.
.SH "OPTIONS"
.PP
\fBxsltproc\fR
accepts the following options (in alphabetical order):
.PP
\fB\-\-catalogs\fR
.RS 4
Use the
SGML
catalog specified in
\fBSGML_CATALOG_FILES\fR
to resolve the location of external entities\&. By default,
\fBxsltproc\fR
looks for the catalog specified in
\fBXML_CATALOG_FILES\fR\&. If that is not specified, it uses
/etc/xml/catalog\&.
.RE
.PP
\fB\-\-debug\fR
.RS 4
Output an
XML
tree of the transformed document for debugging purposes\&.
.RE
.PP
\fB\-\-dumpextensions\fR
.RS 4

HTML
file\&.

.RE
.PP
\fB\-\-maxdepth \fR\fB\fIVALUE\fR\fR
.RS 4

\fBlibxslt\fR(3)
concludes it is in an infinite loop\&. The default is 3000\&.
.RE
.PP
\fB\-\-maxvars \fR\fB\fIVALUE\fR\fR
.RS 4
Maximum number of variables\&. The default is 15000\&.
.RE

\fB\-\-nomkdir\fR
.RS 4
Refuses to create directories\&.
.RE
.PP
\fB\-\-nonet\fR
.RS 4
Do not use the Internet to fetch
DTDs, entities or documents\&.
.RE
.PP
\fB\-\-noout\fR

.RE
.PP
\fB\-o\fR or \fB\-\-output\fR \fIFILE\fR | \fIDIRECTORY\fR
.RS 4
Direct output to the given
\fIFILE\fR\&. Using the option with a
\fIDIRECTORY\fR
directs the output files to the specified directory\&. This can be useful for multiple outputs (also known as "chunking") or manpage processing\&.

Make sure that
\fIFILE\fR
and
\fIDIRECTORY\fR
follow the
\(lqURI reference computation\(rq
as described in RFC 2396 and laters\&. This means, that e\&.g\&.
\fB\-o directory\fR

\fB\-o directory/\fR
will\&.

.RS 4
Pass a parameter of name
\fIPARAMNAME\fR
and value
\fIPARAMVALUE\fR
to the stylesheet\&. You may pass multiple name/value pairs up to a maximum of 32\&. If the value being passed is a string, you can use
\fB\-\-stringparam\fR
instead, to avoid additional quote characters that appear in string expressions\&. Note: the XPath expression must be UTF\-8 encoded\&.
.RE
.PP
\fB\-\-path "\fR\fB\fIPATH(S)\fR\fR\fB"\fR
.RS 4
Use the (space\- or colon\-separated) list of filesystem paths specified by

SGML
catalog behavior can be changed by redirecting queries to the user\*(Aqs own set of catalogs\&. This can be done by setting the
\fBSGML_CATALOG_FILES\fR

/etc/sgml/catalog
catalog\&.

XML
catalog behavior can be changed by redirecting queries to the user\*(Aqs own set of catalogs\&. This can be done by setting the
